Justice Ruth Bader Ginsburg envisions a day when the U.S. Supreme Court is made up entirely of women.

“Sometimes I’m asked the question ‘When will there be enough?’ and I say, ‘Well, when there are nine.’ For most of the country’s existence, there were nine of the same sex and they were all men, and nobody thought that that was out of order,” Ginsburg said at the American Bar Association Section of International Law 2013 Spring Meeting.
